Published: March 2001

The α-selective effect and potency of AgPF on readily prepared 2-deoxythioglycosides allows the direct attachment of a partially protected allo-sugar, such as L-mycarose, to an advanced and hindered aglycon unit of kedarcidin. This method also permits access to other 2-deoxyglycosides in an expedient and mild manner. PMBM=p-methoxybenzyloxymethyl, Alloc=allyloxycarbonyl, TES=triethylsilyl.

Adapting biological systems for nanoparticle synthesis opens an orthogonal Green direction in nanoscience by reducing the reliance on harsh chemicals and energy-intensive procedures. This study addresses the challenge of efficient catalyst preparation for organic synthesis, focusing on the rapid formation of palladium (Pd) nanoparticles using bacterial cells as a renewable and eco-friendly support. The preparation of catalytically active nanoparticles on the bacterium VKM B-3302 represents a more suitable approach to increase the reaction efficiency due to its resistance to metal salts.

Background: Different doses of radiotherapy (RT) exert diverse effects on tumor immunity, although the precise irradiation method remains unknown. This study sought to elucidate the influence of combining different doses of RT with immune checkpoint inhibitors (ICIs) on the infiltration of CD8T cells within tumors, thereby augmenting the anti-tumor response.

Methods: Constructing a mouse model featuring bilateral lung cancer tumors subjected to high and low dose irradiation, the analysis of RNA transcriptome sequencing data and immunohistochemical validation for tumors exposed to various dosages guided the selection of the optimal low-dose irradiation scheme.

Building Localized NADP(H) Recycling Circuits to Advance Enzyme Cascadetronics.

Angew Chem Int Ed Engl

January 2025

University of Oxford, Chemistry, UNITED KINGDOM OF GREAT BRITAIN AND NORTHERN IRELAND.

The catalytic action of enzymes of a cascade trapped within a mesoporous electrode material is simultaneously energized, controlled and observed through the efficient, reversible electrochemical NAD(P)(H) recycling catalyzed by one of the enzymes. In their nanoconfined state, nicotinamide cofactors are tightly channeled current carriers, mediating multi-step reactions in either direction (oxidation or reduction) with a rapid response time. By incorporating a hydrogen‑borrowing enzyme pair, the internal action of which opposes the external voltage bias driving oxidation or reduction, a reduction process can be performed under overall oxidizing conditions, and vice versa.

Facile Access to Highly Efficient 3D Printing Using Robust Self-Healing CDs/Polymer Hybrids.

ACS Appl Mater Interfaces

3D printing efficiency, as a key indicator of additive manufacturing technology, directly affects its competitiveness in rapid prototyping, small batch production, and even large-scale industrial applications. Compared with traditional manufacturing methods, the high efficiency of 3D printing is often considered a bottleneck, hindering its application across various fields. Herein, a versatile and efficient strategy is proposed, namely, the dimensional reduction printing (DRP) process, to break the obstacle of high efficiency of 3D printing.

Directional emission sources are required in wide application scenarios such as 3D displays and optical communication. The integration of beam deflection metasurfaces on emission devices can construct a compact directional emission source. However, most reported metasurfaces and metagratings focus on the deflection of linear polarized light with relatively small angles(< 30 degrees), which limits their further application for unpolarized light sources.
